Chemosis is the swelling (or edema) of the conjunctiva. The term derives from the Greek words cheme and -osis, cheme meaning cockleshell due to the swollen conjunctiva resembling it, and -osis meaning condition. [1] The swelling is due to the oozing of exudate from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of ...
Frequent blinking exacerbates mechanical dry eye symptoms, while increasing blinking improves symptoms of aqueous tear deficiency dry eye. Diagnosis can be further made under a slit lamp upon the observation of redundant conjunctival folds. These folds can be made more apparent by staining with fluorescein dye and by applying gentle upward ...
Orbital cellulitis commonly presents with painful eye movement, sudden vision loss, chemosis, bulging of the infected eye, and limited eye movement.Along with these symptoms, patients typically have redness and swelling of the eyelid, pain, discharge, inability to open the eye, occasional fever and lethargy.
When infected with AHC, patients will experience painful, red eyes, swelling of the conjunctival tissue, and frequent mucus discharge from the eyes accompanied by excessive tearing and subconjunctival hemorrhaging. This hemorrhaging is caused by the rupture of blood vessels beneath the conjunctiva giving the eyes a bright red appearance.
Conjunctivitis, also known as pink eye or Madras eye, [4] [5] is inflammation of the conjunctiva and the inner surface of the eyelid. [6] It makes the eye appear pink or reddish. [1] Pain, burning, scratchiness, or itchiness may occur. [1] The affected eye may have increased tears or be "stuck shut" in the morning. [1] Swelling of the sclera ...
Neonatal conjunctivitis by definition presents during the first month of life. Signs and symptoms include: [citation needed] Pain and tenderness in the eyeball; Conjunctival discharge: purulent, mucoid or mucopurulent (depending on the cause) Conjunctival hyperaemia and chemosis, usually also with swelling of the eyelids
A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris.
[2] [3] Generally only one eye is affected. [2] Causes can include coughing, vomiting, heavy lifting, straining during acute constipation or the act of "bearing down" during childbirth, as these activities can increase the blood pressure in the vascular systems supplying the conjunctiva. Other causes include blunt or penetrating trauma to the eye.
